How can I raise the audio volume on a dvd?

[slipknotmr]

So I have a couple of dvds where the audio volume is low. I'd like to reauthor them & raise the audio level. But I don't want to do anything too advance like exporting audio or resyncing the audio, ext. Just something simple. Is there such a thing? thanks

I just read your reply about this thread in the other one 8)

Well, you will have to demux the audio & video & then raise the audio volume, save it and import it back into the authoring program with the video.

Are you using TDA with the AC3 plugin ?

You could demux the audio & video once it is on your HDD with DGIndex to get the audio in WAV then raise the volume, and save it without changing or adding, then if you have the AC3 plugin for TDA it will convert it back to AC3.
Or you can use it to convert it first.

As long as you dont cut anything out or add anything to the audio it should remain the same length so there will be no problem with resyncing it.

It's worth the $$, i think it's like $20.00 and i use it alot for menu audio in DVD-lab PRO also & by itself.

It all depends on the tools you have or want to pay for as i don't use very many free tools.

Wow being a bit of a newbee this seems a bit complicated( but probably isn't as bad as it seems)
Yes I do have TMPG w/ the ac3 plugin. So how do I demmux the audio & video & most importantly how do I get it back with the video. And is it pretty hard? Thanks!!!

Depends on the software you are using. Most editors allow for simple adjustments of the audio, I always drop a a normalize filter on the audio track which brings the levels up to normal level throughout the clip...

Hi thecoalman, I use TMPGnc & I don't see an audio adjustment feature. What program do you use? Thanks

The simplest solution of all - use the volume knob on your TV. No demuxing required.

Turning up the TV doesn't help much when the volume is this low. I turn itall the way up & the sound doesn't get much loaded. Just the hiss

If the audio is AC3 use the "dialog" setting in the DVD player setup,if you don't have that setting lower the dynamic range.Demuxing and normalizing AC3 can lead to synch problems.
If the audio is MP2 or LPCM then use TMPGEnc ->Setting->Audio tab->Audio Edit.

I wouldn't expect there to be one. That's a single function tool, single function tools are fine and provide a greater control than ones that provide muti-functions.

Edit: I see moviegeek pointed you in the direction for the audio in TMPGenc.. Good Luck.

I use an advanced editor which gives me control and many features, unless you want to get really creative with your video that is not solution for you. Most of the low end editors have this feature though... Ulead Video Studio is one. Most of the purists shudder at the thought of using a tool like this but it does produce good results and if simplicity is what you want VS or something similar is the ticket. If you don't have a editor I'd suggest VS, it's packed with editing capabilities. You can still use TMPGenc for encoding...

The main vid I'm trying to fix is a concert vit. It's pretty quite & a bit hissy when I turn it up. One thing that worries me is if I rais the level it's just gonna make the hiss louder. I'm wondering if it's even worth my while( or is there a way to de-hiss it? Thanks

[guns1inger]

Sounds like you need to do a lot more work that just adjusting the volume. If you really want to fix it then you will have to demux the audio, adjust the volume and spend some time adjusting EQ settings etc to filter out as much hiss as possible (this is a good starting read http://digitalfaq.com/dvdguides/restoration/audio/intro.htm ) then put the audio back in. Not a trivial task, however if you don't edit the sound, you should avoid sync problems.
